18 Floating Point – FNC110 to FNC139
18.2 FNC111 – EZCP / Floating Point Zone Compare
18.2 FNC111 – EZCP / Floating Point Zone Compare
Outline
This instruction compares data (binary floating point) with two values (one zone), and outputs the comparison result to
three single bit devices.
→ For handling of floating point, refer to Subsection 5.1.3.
1. Instruction format
2. Set data
*1. When a constant (K or H) is specified, it is automatically converted from binary into binary floating point (real
number) when the instruction is executed.
3. Applicable devices
S: "D.b" cannot be indexed with index registers (V and Z).
Operand Type Description Data Type
